A DESCRIPTION OF SOME TA8MANIAN SKULT.S SMITH. 25 



Hues pass backwai-ds over the most prominent part of the 

 parietal eminences. The anterior part of the sagittal suture 

 runs in a narrow groove on the median crest. The groove in 

 this skull widens out posteriorly to a slight extent. One 

 might say that tlie crest becomes somewhat flattened in the 

 region of the obelion. 



Norma laferalis. — Tlie forehead is flattened. The glabella 

 is not well marked, but the superciliary ridges are large and 

 stand out like uodnlar masses. They are separated from the 

 supra-orbital borders by shallow, indistinct grooves. On each 

 side the trigonum is flattened, but the external orbital 

 processes are thick* The supra-orbital depressions are well 

 marked. The nasion is deeply depressed ; the inter-nasal 

 suture, measured in a straight line, is 11 mm. long. The 

 profile outline of the nose is slightly concave, and the nasal 

 bones form a slight ridge at their sutural junction. The frontal 

 arc is 130 mm long; the parietal is 120 mm. The length of the 

 occipital cannot be determined. 



Norma facialis. — The nasal spine is distinct, though not 

 large. The nares are fairly wide, the index being 57.4. The 

 infra-orbital foss© are very deep. The fronto-malar border 

 of the orbit is thickened and rounded. The orbital index 

 is 73.8. 



The sutures are well marked. None of them are obliterated 

 at any part. The coronal is simple ; the lambdoid is partly 

 denticulated ; and the sagittal is denticulated in its whole 

 length.
